To au why-0.7i?, it 71mg concern:

Be itknown that LRALPH V.. SAGE, a citizen of the United States, residing in the borough of Westmont, in the county of Cambria andv State of Pennsylvania, haveinvented'certain new and useful Improvements in Car-Bolstersgand I do hereby declarey the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists of various improved constructions of -car-bolsters andthe details thereof, with particular `reference 'to those known as truck-holsters, certain of the objects of my invention being to produce a structure which is well adapted to withstand the various stresses to which it is subjected in use, simple, cheap, and formed of materials that may be readily and economically procured and fabricated.

My improved bolster has thefreneral form of a box-girder, deeper at the center than at the ends, the top and side members of said girder being combined and formed from Aone plate by bending or flanging it in straight lines, the'lower portions of said plate .forming the sides or Webs of thebolster being cut tapering from the center to the ends in each direction, so as to form a girder of greater depth at the center than at the ends, as heretofore stated. The manufacture of a plate of this description is a very simple matter, as it only has to be sheared to shape and then bent or flanged in straight lines without any distortion or buckling of the metal. Between the lower edges of the webs so formed I place a bottom member, preferably of channel .or trough section, the flanges of .\7vlrich,;`

adjoining and parallel to,V the said webs, whereby the bottom member project outwardly,

may be connected to the Webs by machinerivetingin the customary manner, which is a' very ecient and cheap method of manufacture. On the top of the bolster Iyrivet a cover-plate for addingstrength and stift'ness to this portion of the struc-ture and to serve as a support for the center plate, which may be of any usual form, attached thereto. At

5o-`the ends of my bolster I provide end yokes formed of plates bent in trough or channel form, on the outer sides of which I placethe end yokes and column-guides being securely att-ached by through rivets or bolts to the webplates of the structure. v

At tile center of the bolster I provide a diaphragm composed of two channels, the central portion'of the webs of which are pressed in the form of semicircles, so that when these two channels are placed back to back and riveted in position they form a brace for the main structure, a support for the load trans. mitted through the center plate, and a hole for the king-pin, which rests in the opening formed between the channel-webs.

In order to further stiilen and adapt the structure for the use intended, I also provide end braces or diaphragms, preferably formed of channels riveted to the web of the bottom channel and to the top member of the main construction. I also further provide side bearings on the top of the bolster, which may be of any usual form, and brackets for attaching ,the brake-rigging. p l Having thus given a general description of my invention, I Will'now inorder to make the matter more clear refer to the annexed sheet of dra wings,which form part of this specification and in-which like figures refer to like parts. Figure l is aside elevation of my bolster. Fig. 2 is a plan thereof. Figl 3 is' an end elevation, and Fig. 4 is a central'vertical sectional elevation on the line A A of Fig. 1.

Referring now to the various characters of reference upon the drawings, l is the com- .bined web and top `member or U-plate, of trough or channel form', deeper at the centerl than lat the ends. t

2 is a cover-platel secured to the central portion of the top of the bolster, as shown,

f 3 is the bottom member, shown as a channel,` bent to conform with the lower outline of the structure and secured between the web or side plates l by means of rivets, which may be driven from the exterior, as clearly indicated.

4 is a center bearing, and 5 represents the side bearings, both of which may be of any usual form or construction'. As shown in the various views, @represents the center' braces, formed ofchannels, the webs of which are formed so that'whenthe channels are placed back to back,i as indi-..-

IDO

cated, a cylindrical opening l2 lremains forl the reception' of the hing-pin, said channels 6 serving as a brace for the structure at the center, to the sides of which it is riveted, as' shown, also serving as a support for the load which comes 'upon vthe cent-er; plate. The dead-lever guide-fulcrnm for the brake-rigging isindicated at 7.

S represents inside end braces or-diaphragms, shown as channels, riveted to the top mem-ber and to the web of the bottom 10 represents "the end yokes, preferably formed of plates, bent in U shape, as shown,.

the flat bottoms ot which serve' as bearings for transmitting theload to the truck through the eustomarysprings or their equivalents.

1ll represents ycolumn-guides formed of crimped plates', as shown, thesev end yokes and column-guides being secured to the Webs l bythrough bolts or rivets, as indicated on the-drawings. l

13 represents hand-holes formed in the top member'tor convenience in inserting yrivets or' bolts when repairing or assembling the structure, although itwill be noted from the drawings that the whole design is such -that most of the work .of Iriveting or securing the various parts together Vcan be vaeetmiplished from the outside, thus conduciug to ease and economy of manufacture and repair.v

Althonghl have shown my improvements in eonsiderabledetail, I do not limit myself to the exact and specific particulars of the arrangement of sections shown and described, but vmay use 'such substitutions, modifications, or equivalents thereof as are embraced Within the .scope ot' Amy invention and as pointed ont in the claims.

I Having thus given a description'ot my in- Vention, what I .desire to' secure by Letters Patentl isv l.y In a bolster, a combined tpp and sidemember consistiugof a plate bentin channel or trough form, the sides being deeper at the center than at the ends, abottom member of' channel-section secured to the lower portion of the side membersfby its externally-pro ]'ect, ing flanges;y f
